Although risk factors for hospitalization from a respiratory syncytial virus (RSV) are well known, RSV lower respiratory tract infections (LRIs) in the community are much less studied or understood, especially in developing countries. In a prospective, cohort study we studied factors predisposing Indonesian infants and children under 5 years of age to developing RSV LRIs. Subjects were enrolled in two cohorts: a birth cohort and a cross-sectional cohort of children <48 months of age. Subjects were visited weekly at home to identify any LRI, using the World Health Organization’s criteria. RSV etiology was determined through analysis of nasal washings by enzyme immunoassay and polymerase chain reaction. Risk factors for the development of the first documented RSV LRI were identified by multivariate analysis using logistic regression and Cox proportional hazard modeling. Of the 2014 children studied, 999 were enrolled within 30 days of birth. There were 149 first episodes of an RSV. Risk factors for an RSV LRI were poverty (p < 0.01), use of kerosene as a cooking fuel (p < 0.05), and household ownership of rabbits and chickens (p < 0.01). Our findings suggested that in a middle-income country such as Indonesia, with a substantial burden of RSV morbidity and mortality, lower socioeconomic status, environmental air quality, and animal exposure are predisposing factors for developing an RSV LRI.

Abstract Background Acute lower respiratory tract infections (ALRIs) especially severe ALRIs, constitute a global high burden of morbidity and mortality in children <5 y of age and respiratory syncytial virus (RSV) has been documented to a play a major aetiological role. However, Nigerian reports on severe childhood RSV ALRIs are rare and most reports are old. With recent advances in RSV preventive strategy, arises the need for a recent appraisal of RSV infection in children with severe ALRI. The current study thus set out to determine the prevalence of RSV infection among hospitalized children <5 y of age and describe the related social determinants. Methods We performed a descriptive cross-sectional study conducted over 1 y of 120 children, ages 2–59 months, diagnosed with ALRI. Relevant data were obtained and an antigen detection assay was used for viral studies. Results The prevalence of RSV infection was 34.2% and its peak was in the rainy months. The proportion of infants in the RSV-positive group was significantly higher than that in the RSV-negative group (82.9% vs 54.4%; p=0.002). These findings were largely consistent with those of earlier reports. Conclusions RSV has remained a common cause of severe ALRI in infants, especially during the rainy months in Nigeria. It is thus suggested that more effort be focused towards implementing the current global recommendations for the prevention of RSV-associated LRI, particularly in infants.

Respiratory syncytial virus (RSV) is an important community and nosocomial respiratory pathogen for infants and young children. RSV causes especially severe disease in the prematurely born or those with chronic cardiopulmonary diseases. Elderly persons and those with T-cell deficiencies, such as bone marrow transplant recipients, are also at high risk for serious lower respiratory tract infections. To date, prevention of RSV infections by vaccination has proven elusive and no preventive drugs exist. Studies in animals and humans have shown that the lower respiratory tract can be protected from RSV infection by sufficient circulating RSV neutralizing antibody levels. Recently, an RSV hyperimmune immune globulin (RSVIG) was developed and tested for the prevention of RSV infections or reduction of disease severity. Passive immunization of high-risk children with RSVIG during the respiratory disease season effected significant reductions in RSV infections, hospitalizations, days of hospitalization, intensive care unit admissions, days in the intensive care unit, and ribavirin use. Studies in cotton rats and owl monkeys show that RSV infections can also be treated with inhalation of immune globulin at doses substantially smaller than required for parenteral treatment. Therapeutic trials of parenteral RSVIG have been completed and are pending analysis. The use of polyclonal, hyperimmune globulins and perhaps human monoclonal antibodies provides an additional approach to the prevention and perhaps the treatment of certain viral lower respiratory tract infections such as those caused by RSV.
